VENTILATING SYSTEM FOR SANITARY TOILETS.

Specification of Letters Patent. I

Patented Dec. 31, 1918.

Application filed December 27, 1917. Serial No. 209,079.

To all whom it may concern.-

Be it known that I, EDWARD J. DE GUENTHER, a citizen of the UnitedStates, residing at Milwaukee, in the county of M11- waukee and State ofWisconsin, have 1nvented certain new and useful Improvements inVentilating Systems for Sanitary Tollets, of which the following is aspecification.

This invention relates to certain new and useful improvements inventilating systems for sanitary toilets.

The primary object of the invention 1s the provision of an automaticallyoperated ventilating system for toilets whereby the same is ventilatedfrom outside of the building when the toilet is not in use and from theinterior of the building when in use.

A further object of the device is the provision of a ventilating systemfor providing a complete current of air through a toilet from one sourcewhen not in use and from another source when in use, thereby renderingthe complete device sanitary at all times.

A still further object of the invention is the provision of a dualventilating system for house toilets automatically operable by the usualdrop or lid for changing the direction of ventilating air therethrough,whereby circulation is uninterrupted, the exhausting of the ventilatingmedium being at a suitable elevation above the building within which thetoilet is arranged, it being understood that the circulating air may beimpregnated with a suitable disinfectant if desired.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination, construction and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings and thenclaimed.

1n the drawings forming a part of this application, and in which likereference characters refer to corresponding parts throughout the severalviews,

Figure 1 is an elevational view of the device partially broken awayillustrating the same installed in a building.

Fig. 2 is an elevational view of the connecting lever and Fig. 3 is atransverse sectional view taken upon line IIIIII of Fig. 2.

Referring more in detail to the drawing 11; will be nrst understood thatmy invention contemplates the positioning of a tank 10 arranged beneaththe floor 11 of a building adapted for holding a quantity ofdisinfecting material such as the fluid 13 while a usual form of toiletbowl 1% is positioned w thin the building 12 upon the upper end of anuprlght pipe or stack 15 mounted upon the said tank.

An intake pipe 16 is arranged entering the tank 10 at the opposite endthereof from the stack 15 with the free end of said pipe 16 pro]ect1ngabove .the surface of the ground 17 provided w'tih a spaced cap .18adapted for normally preventing foreign material from entering the pipel6 but permitting the free passage of outside air into the tank 10through the said intake pipe- The usual vent pipe l9 is arranged for thebowl 11 extending to an elevated point above the building 12. A damper20 is hinged wlthin the tank 11 at the lower end of the pipe 12 forclosing the same and is operatively connected by means of a pivot rod 21with a lever 22 journaled upon a shaft 23 arranged within the tank 10.The drop or lid 24: of the bowl 142 is arranged thereon in the usualmanner and is connected with the lever 22 by means of a curved rod 25.It will be readily understood by referring to Fig. l of the drawing thatwhen the lid 21 is in its normal closed position, the rod 25 will belowered and a damper 20 will be in its normal open arrangement. Air mayreadily enter the intake pipe 16 from outside of the building 12 andafter passing through the tank 10, stack 15 and bowl 14:

freely passes upwardly through the vent pipe 19 exhausting above thebuilding 12. It will be seen that under normal conditions, thecirculation of air through the bowl 14. provides a circulationtherethrough of fresh air which has been passed through the disinfectingtank 10 and this renders the entire device sanitary by reason of itsgerm killing properties.

It will be understood that when the lid 21 is elevated, the rod 25 andlever 22 as well as the rod 21, will be elevated therewith as indicatedby dotted lines in Fig. 1 of the drawing and which operation arrangesthe damper 20 in its closed position at the bottom of the intake pipe16. At such times, the draft caused by the vent pipe 19 will draw airfrom the toilet room 26 within the building 12 and such air will passthrough the bowl 14 and upwardly out of the vent partial rotation to thelatter during each opening movement of the lid 24. An automaticallycontrolled ventilating system for a sanitary toilet is'arranged adaptedfor operation in connection with a disinfecting device for rendering thestructure entirely sauitary and germless.

While the form of the invention herein shown and described is believedto be the vpreferred embodiment thereof, minor changes .may be madetherein without departing froinlthe spirit and scope of the invention asclaimed.
